The present invention relates to a machine for putting a wrapper about a package.

In various manufacturing businesses it is common practice to put wrappers around a, given number of articles as for instance, sheets, curtains, handkerchiefs, shirts, and other things that are sold singly or in lots. One common method is .to have the strips that are used for the wrapping cut to certain definite sizes and then pin the ends of the wrapper together after they are placed around the goods to be wrapped. In other methods it is common practice to apply an adhesive to one end of the wrapper and pass this over the other end of the wrapper or to apply a separate adhesive strip uniting the ends of the wrappers together. In the present invention the wrapper to be applied is fed from a roll of the wrapping material in a continuous sheet and the free end of the band is wrapped about: the package and stapled'or joined to the band at the same time that the band is severed from the strip. This method of wrapping has proved to be extremely economical, not only in the saving of labor, but also in the saving of material. Where the strips are all previously cut, it has been found that a good deal more material is required and further, the wrapping takes longer and therefore imposes upon the manufacturer a higher labor cost.

In the present method of wrapping, the ends of the strip are joined together in face to face relation, preferably by means of a metallic staple as for instance the kind that may besupplied from a I-Iotchkiss or Bostitch. machine. In the present invention the strip is continuously fed, and when the strip has been severed and the binding completed, the strip is again served, the package laid in position to be wrapped and the stapling and severing lever pressed tocomplete the binding of the goods.

The operation of the machine and the advantages gained in the use of the device and I method of the present invention will be more fully explained in the description of the embodiment of the invention given below in connection with the drawings, in which:

Figure 1 shows a side elevation of the machine as it may be mounted on a factory bench.

Figure 9 showsa detail used in Figures 1 and 2. v

In .thedrawings referring particularly to Figure 5, the wrapping band is supplied in a roll I which may be mounted in the side supports of the device on the roller 2. The strip indicated atv 3 passes under the guideroller 4 and through 15 the guide 5 on to the platefi which extends from the support I beneath the guide 5 to a position between the lower roller 8 and the upperlroller 9, the plate Ghaving extending arms Ill and I I resting inthe recesses I2, I2 in the roller 8. The top roller ,8 engages the strip so that when the roller 8, operatedas indicated in Figures 1, 2, 3 and 4 isrotated, the paper strip, which of course may be also of any other material, is advanced over the plate 6 and thespring plate I3 to the platform or stapling and guiding plate I4. The, spring strip I 3 it will be noted is mounted on the support I5 and the end of the spring is given ,normally an upward tilt which extends slightly above-the surface of the plate I4. The stapling and cutting .mechanism is positioned above the plate I4. This'comprises a stapling device I5 of any of the usual types with an extending barrel It for holding a sufficiently large number. of staples. The machine is supported in a frame which is made up of two side plates II and i8 with upwardly extending brackets I9 to which the barrel I6 is pivoted by means of the shaft-2t with the pivots extending into the sup ports it as indicated, more clearly by the pivot 2 I of Figure 5. machine is also pivoted by means of the barsZ'Z and 23 in the'upper portion of the bracket I9 through the shaft 23 journaled into the support or bracket I9 and the pivots 24 at both ends of the shaft. These bars 22' and 23 also support the'stapling shaft 25. The pin or rod;26- passes transversely through the stapling shaft 25 and extends into the ends of the bars 22 and E3, the shaft 25' being held in position by means of the sleeves 2i and 28 positioned between the shaft 25 and the bars 22 and 23 and surrounding the rod 26. The lower end of the stapling device carries a cutting plate 29, which as it descends, comes in contact with the cutting shoe package as B of the guide element The upper portion of the stapling 0 30 thus severing the band from the rest of the roll. This cutting plate may be shaped as indicated in Figure 6 and be provided with a plate of special design as indicated by the curve 3|. Both the cutting and stapling is operated simultaneously through the foot lever 32 of Figure 1, which when pressed draws the bar 23 downward and presses downward the stapling shaft 25 and the cutting plate 29 towards the plate I4 and cutting shoe 30 respectively. A stapling spring mechanism 80 may be provided so that when the foot lever is released the stapling machine springs back to the normal position indicated in Figure 5. When this is done the spring plate I3 automatically raises the paper strip on it above the plate I4 so that when the next portion of the strip is served, it will pass over the plate I4 and be in a position to be stapled and severed by the succeeding operation of the foot lever 32. A strip serving mechanism is indicated in Figures 1, 3 and 5 particularly. A lever 33 which is joined to a segment 34, is included, pivoted at 35. The segment 34 has a set of internal spur gears meshing with the spur gear 31 which is carried by the end of the shaft 36 upon which the roll 8 is pinned by means of the key 31 as shown in Figure 4. Also mounted on the shaft 36 is the ratchet 38 and the pawl 39 mounted on the frame engaging in the ratchet so that the shaft 36 and the ratchet 38 will only rotate in the direction of the arrow 39' as indicated in Figure 4. In this way when the lever 33 is pulled forward in the direction of the arrow 40, the roll 8 will be rotated to advance the strip a definite amount depending upon the amount the lever 33 is allowed to move. In this way all paper will be fed the desired length over the plate I4.

A guide may be provided just beyond the point to where the paper is severed so that the strip is properly guided into its final position. As indicated in Figures 8 and 9 the strip 5I has its two endsEZ and 53 in face to face relationship with the staple 54 passing through both strips 52 and 53 and turned over on the other side as indicated by the ends 55 of the staple. In the operation of the parts, the operator simply places the package over the strip with the edge 56 adjacent to the end of the strip which is to be cut and stapled. The free end of the strip is then brought over in face to face relation with the strip itself and the lever 32 is pressed bringing down both the stapling shaft 25 and the cutting knife 29.
